Wasps have defended James Haskell after World Cup winner Lawrence Dallaglio criticised his absence from their 57-33 Aviva Premiership play-off defeat at Saracens in order to attend the Royal Wedding at Windsor Castle.

Following eight months of intense competition four teams are left battling for silverware in the Aviva Premiership and PRO14, while Castres, Lyon, Toulon and Toulouse target a place in the Top 14 semifinals.

Jack Willis could be forgiven if he was caught basking in his early success. But the England hopeful is well aware that rugby careers are fleeting as he attempts to help mentor James Haskell leave Wasps as a Premiership champion.
